SUPPORTING STRUCTURE.

Application filed October 5, 1912.

To all whom it may concern:

Be it known that I, L.\ Vnnxn IV. News, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Supporting Structures, of which the following is a full, clear, concise, and exact description, reference be in g had to the accompanying drawings, forming a part of this specification.

My invention relates to supporting structures and is of particular service in connection with the formation of wind mill and tank supporting towers. Such structures are commonly formed of L-shaped iron and bracing elements of L-shaped iron are usually provided between the sloping pillars of Intermediate portions of these bracing elements engage other bracing elements and in order that these various bracing elements may be properly directed and united the first aforesaid bracing elements were partially collapsed by bringing the middle portions of their angularly related walls into parallelism. Such a collapsing'would obviously weaken the collapsed braces and it is the object of my invention to avoid such collapsing while at the same time maintaining the desired number and interrelation of the various bracing elements at the base of the structure. Such a structure of the prior art is exemplified by my Patent 889,395, dated June 2, 1908.

My invention will be fully explained by reference to the accompanying drawing showing the preferred embodiment thereof and in which Figure 1 illustrates a tower in elevation, the top and base portions of the tower being. alone shown as there is insuflicient space to illustrate the intervening portions of the tower; Fig. 2 is a sectional plan View of apart of the structure on line 2 2 of Fig. 3; Fig. 3 is a view in elevation of the novel portion of the structure; and Fig. at is a view taken in the direction of arrow 4 of Like parts are indicated by similar charactors of reference throughout the different figures.

The to own includes three equidistant o was a a a that converge to- Specification of Letters Patent.

as is well known by those familiar with the art. Inclined braces b are secured to and intervene between the base portion of each pillar a and suitably high portions of the remain ng pillars, the braces uniting the same pillars being crossed at a, there being thus three pairs of braces b, the members of each pair being united at 0, preferably by riveting. The pillars of each pair which are united by a pair of braces b and also further united by a horizontally or transversely disposed brace d, the ends of this brace (I being riveted to the pillars united thereby while the intermediate portion ofthis brace cl crosses the associate braces b below their ]l1I1Cl31OI1 point 0 and being riveted to the braces 12 at c. at 6 might be accomplished it was hitherto the practice merely to collapse the intermediate portion of one ofthe walls of the brace (Z to bring the central portions of the walls of this brace in parallelism in order that the riveting might be accomplished, this result being gained at the expense of destroying the character of the brace 61 as an L-shaped iron element at the central portion thereof. In accordance with my invention the two halves of each brace d are twisted between the associate braces Z) so that the angularly related walls of each half of each brace d are substantially at right angles with their respective continuations in the other half as will be clearly apparent by an inspection of the middle portion of Fig. 1 and the enlargement of the illustration of this portion contained in Fig. 3. The braces b of each pair obviously have an angular wall portion of each parallel with an angular wall portion of the other, these two wall portions meeting in a common plane and occupying closely approximated planes from their junction point to the junction thereof with the transverse brace. In order to complete the structure of my invention, as the invention is preferably practised, the brace d is bent so as to have one half upon one side of this plane and the other half upon the other side of this plane as illustrated most clearly in Fig. 2, in which event the left hand end of the brace d is riveted/upon the outside of the left hand sloping pillar a and the right hand end of the brace d is riveted to the right hand pillar a between the angular walls of this right hand pillar. In this Patented Dec. 15, 1914. j

In order that the riveting "of my invention it is obvious that changes mayfreadily be made without departing from the spirit thereof and I do not therefore wish to be limited to the precise details of construction shown, nor to the bending' of the member d, in all embodiments.

' Having thus described my invention I claim as new and desire to secure by Letters.

Patent the following 1. A supporting structure including corn'er pillars and three L-shaped iron braces eachcrossing the others and secured to and intervening between adjacent pillars, two of these L-shaped iron braces having wall portions thereof closely adjacent, substantially parallel, and joined together where these two braces cross, While the third L-shaped iron brace is joined with the aforesaid joined wall portions upon one side of the junction of said wall ortions which are upon opposite sides of the third brace, the third L- shaped iron brace being twisted between the other two braces to cause two portions of each of its Walls to be angularly related to make its walls where joined with the other braces substantially parallel with the aforesaid wall portions of the other two braces and having one of its walls fastened to one of the other two braces and the other wall fastened to the remaining brace, the first aforesaid joined wall portions substantially continuing in the same closely approximated planes from their junction with each other to their junction with the third brace which is bent at a place between the other two braces to bring the walls of the third brace into engagement with the Wall portions of the other two braces where junctions between these wall portions and the third brace occur.

2. A supporting structure including corner pillars and three L-shaped iron braces each crossing the others and secured to and intervening between adjacent pillars, two of these L-shaped iron braces having substantially parallel wall portions while the third L-shaped iron brace is joined with said parallel wall portions upon one side of the place of, crossing of said parallel wall portions which are upon opposite sides of the third brace, the third L-shaped iron brace being twisted between the other twobraces to cause two portions of each of its walls to be angularly related to make portions of both of its walls substantially parallel with braces joined therewith.

8. A bracir g structure including three L- shaped iron braces each crossing the others, two of these L-shaped iron braces having substantially parallel wall portions while the third L-shaped iron brace is interposed between said parallel wall portions upon one side of the place of crossing of said 'parallel wall portion, the third L-shaped iron brace being twisted between the other two braces to cause two portions of each of its walls to be angularly related to make portions of both of its walls substantially parthe respective wall portions of the other 'two 1 allel with the opposing wall portions of the my name this second day of October A. D.,
